Grapevine: Tweeting trouble for MSNBC

The MSNBC official Twitter account has landed the network in some hot water, again.

Last night this tweet was sent -- quote -- "Maybe the right wing will hate it but everyone else will go awe -- the adorable new Cheerios ad with biracial family."

Attached was a link to this commercial showing a biracial family.

The RNC chairman asked for an apology to the RNC and all right-of-center Americans and threatened a boycott -– quote -- "Using biracial families to launch petty and ridiculous political attacks is low, even by MSNBC's standards. It only coarsens our political discourse."

This afternoon, MSNBC's president released a statement about the tweet -- quote -- "We immediately acknowledged it was offensive and wrong, apologized and deleted it. We have dismissed the person responsible for the tweet. I personally apologize to Mr Priebus and to everyone offended."

Priebus has accepted the apology, but the tweet is the latest in a string of recent issues in recent weeks for MSNBC.
